A combination is a selection of part from a set of objects. In a combination the order of selecting object does not matters.
So we use combination for selecting 3 from the population of 10
We know combination of selecting 'r' objects from 'n' is nCr
We need to find 10C 3
= 120
120 different samples of size 3 can be taken from a finite population of size 10
Answer:
Step-by-step explanation:
This inequality is quite simple to solve.
Just multiply both sides by four and you have your answer:
Hope this helps!
Substitute x for -1 in <span> y=3x-1
</span>y = <span><span>(3) <span>(-1) -</span></span><span>1
</span></span>Solve
y = (3) (-1) -1
y = -3 - 1
y = -4
B.) -4 is your answer
Answer: I'm pretty sure it would be no
Step-by-step explanation:
18. $18 + $16 + $6 = $40
20. $300 - [3($39) + 2($62)]
= $300 - ($117 + $124)
= $300 - $241
= $59
Therefore, yes, he has enough money.
22. L = 26 W = 14
Perimeter = 26 + 26 + 14 + 14
= 80
Cost = 80ft * $13/ft
= $1040
